Trang 1Lab 2.2.9 Command Line Fundamentals
Objective
• Log into a router and go to the user and privileged modes
• Use several basic router commands to determine how the router is configured
• Use the router HELP facility
• Use command history and editing features
• Logout of the router
Background/Preparation
HyperTerminal is a simple Windows-based terminal emulation program that can be used to connect
to the routers console port A PC with HyperTerminal provides a keyboard and monitor for the router Connecting to the console port with a rollover cable and using HyperTerminal is the most basic way
to access a router for checking or changing its configuration
Set up a network similar to the one in the diagram Any router that meets the interface requirements may be used Possible routers include 800, 1600, 1700, 2500, 2600 routers, or a combination The configuration output used in this lab is produced from a 1721 series router Other routers may
produce slightly different output
The following resources will be required:
• Workstation with a serial interface and HyperTerminal
• Cisco Router
• Rollover, or console, cable for connecting the workstation to the router
Trang 2The following steps are intended to be executed on each router unless specifically instructed
otherwise
